T0 (ZZZ whom it may concern;

Be it known that-I, HARRY T. T EILARE, 'a citizen of the United States, residing at Rochester, in the county 'ef Olmsted and State of Minnesota, have invented oeitein new and useful Improvements in Phonographs, of Which the following is tspeciiie'etion.

This invention Telttt'es to I certain new iii'tl useful iliipi'oveirlen'ts in phonogiaphs, iili'tl has peitieuleireference to it setting mecha- Iiis'm for the tone *aiih's oi phono'gftphs.

It is well known timt coiisid'erabie dhit oulty is experienced with 'eommei-eiel pho- IIO'gI' EIPhS i 11 flOCLtI'htlY setting the tone 'M'ihs so that the needle of the s iii he): engages the SO'ufid groove of the ie'eoi'd at the starting point of the gi'oo've, It itCCOlClili "1V, ah o-bjeet of the pieseht hivention to pres 5 e me ns for setting the tohe aiii'is in proper position atiiol'ffol" lowe ing the same to ehgage thenedleef the s und box with the sound groove at the starting oint thereof.

Another object of the ihveiition is to 1310- Vic-lie nie'ttiis iorhmfi the tone afm ftoin opera vs to imperative position, or vies- Versa, and nieeiis coopei' att ihg with thetone aim hi'oviiig' means for scent-stew liihit'ihg swinging movement of the szugiie to it poiht, whereby when the tone arm sound he): needle will ztecui'ately engvge the starting point in the sound "groove of the record. I

Still another objeet of the i vention is the provision of limiting means whereby the swingi g movement of the tone Li-1n Wiilhe limited to e proper poiht iI'i a'eoofdimoe With the size of the recoifi t0 heplayecl.

Nith the above general objects in View, and others that will become a parent as the ligature of the invention is better understood, the same consists in the novel form combination, and zii'hiuilgeiheht of putts herein after more fully described, shown in the ne- GOHiplIiyiITQ; drawings, and (31a lied.

Refs" iiig more in detail to the drawings,

the iiii' e'i' ion shown e1 plied to e. commie]:- elai type out disk phoiiogmph, embodying there-m1 easing oi eihinet 5, Within whieh loc ted the usual hei'li 0ihinpliifyiiig iiiei'nbet 6, and above the top of which is located the usual tui'n tztble 7, adapted for ieoeption of a disk lGCOid 8. Dis osed above the turn table is the ihtvai'clly prej eting tone arm 9, having a sound loo-i; 10, which is adapted to receive a needle in the usual i i-itinner message thesound groove of the record 8 folreprochieing the souiid i-eeoifled there- In this type of i'l lac-l'iine, the tone ttl'ln and horn GtfGi-Tl iiiie'cl relation to each other and pivoted to as the tone ii r in moves towti'ds the center of the record during the playin of the record, the horn and tone him being also ei celly mowble to engage and disengege the needle 01" styles from the record;

In accordance with the present invention, a Vertical rook shzi'itt 11 is suitahly joui'nzilecl tit theta-Ward 611d "of the casing in front of the li'din 6, and hes a tt'ezu'wai oliy projectin ZLl'Hl 12, as shown in Figure 3, which is juttach'ed to the arm as at 13, so that when the sheftll is turned in'eitlie1"lifeetioi1, corresponding swinging movement is imparted to the tone arm and the born. In ordeito prevent rez'itly turningof the shaft 11, the same is provided with a cam leVeI' 14 upon its up pet (and above the top Willi 15 of the cabinet 5, which chin level.- '14 is raised for p'ei'h'iitiieiit of the rock 55111111 11 for eieespohdmg1y loitering the (one arm iiiol hem, asindiestscl h dotted lines in Fights .2, in which lowered positimi the needle or stylus engages the sound ow of the record 8. Oh the other hziii'cl, when the Cain level" 14 is lowered to the rvosition shown in Figure 2, the horn and soun'clbok, as Well as the tohe arm is in raised position out of engagement with the record.

The lower end of the rock shaft 11 is pi-otitled with a stop arm" 16, Whieh is suitably I fastened thereon as by means of a set screw starting point of the groove in the record 8.

This means embodies a guide 18 preferably in the nature of a vertical bracket fastened to the bottom of the cabinet 5 and having vertical end flanges in which is guided a vertically movable plate 19 having stop lugs 20 and 21, which are arranged in the path of the arm 16, selectively, and in a manner path of the arm 16, the movement of the tone arm 9 is limited to the proper point when a small size record is to be played. while when the lug 21 is disposed in the path of said arm 16,. the tone arm 9 is allowed to swing a lesser distance for properly positioning the stylus with respect to the starting point of the groove in a larger record.

The upper end of the slide 19 is attached to the lower end of a rod 22 which extends upwardly through the top of the cabinet 5 and terminates in a knob 23 by means of which, the slide 19' may be conveniently raised or lowered in order to place the desired one of the lugs and 21 in operative relation to the arm 16. Means is provided for retaining the slide 19 in any of its vertically adjustedpositions'such as a spring pressed plunger or ball catch 24 carried by the bracket 18 and adapted for selective reception within suitable sockets 25 provided in superimposed relation on the back of the guide 18. As shown in Figure 6, the arm 16 is of peculiar construction embodying a main section with a pivoted member 26 upon the outer end thereof, which member ishinged on the pin 27 for vertical swinging move ment and has a longer inner edge portion 28 whereby the outer end of the member 26 is normally maintained horizontal, as shown in the above mentioned figure, and by means of which the arm is allowed to tilt under the influence of the lugs 20 and 21, as will presently become apparent.

As shown in Figures 2, 4 and 5, the lugs 20 and 21 are in spaced super-imposed relation so that when the tone arm and horn are lowered, to engage the stylus with the record,

the arm 16 is lowered to a point wherein its outer end portion 26 may pass between said lugs as it moves with horn and tone arm during the playing of the record. When the record is played, the arm 16 will have moved to the opposite sides of the lugs 20 and 21, and as it is necessary to raise the arm 16 with the tone arm 9 in order to disengage the stylus from the record and then swing the tone arm back to starting position, it is necessary to provide means whereby the arm 16 may readily pass in the opposite direction without being prevented from having this movement by the lugs 20 or 21. For this purpose, the lower edges of the lugs are of cam formation or curved as at 29, so that the outer end 26 of the arm 16 will engage the curved surface, and be caused to tilt downwardly. hen the member 26 of the arm 16 passes the lower point on the edge 29, it will immediately swing upwardly to the position shown in Figure 6, so as to be in position to engage the fiat side of the lug arranged in its path upon the positioning of the tone arm upon a new record to be played.

In operation, the cam lever 14 is lowered to the position shown in Figure 2, and is then rotated to the right, so as to swing the tone arm 9 in the same direction out of the way. The record is then placed upon the turn-table, and the lever 14 is swung to the left until the member 26 of the arm 16 strikes against the fiat side of the lug 20 or 21, which is arranged in its path. It is of course to be understood that if a ten-inch record is to be played, the slides 19 will be lowered so as to place the lug .20 in the path of the member 26, and if a twelve-inch record is to be played, the slides 19 will be raised to dispose the lug 21 in the path of said arm member 26. In this way, the movement of the tone arm 9 to the left is limited to a proper point wherein the stylus is disposed directly above the starting point of the groove in the record. When the movement of the lever 14 and tone arm 9 is then limited, the lever 14 is then raised so as to permit of the tone arm and horn together with the shaft 11 to lower to the position shown by dotted lines in Figure 2. When so disposed, the needle or stylus is arranged in the groove of the phonograph and the member 22 of the arm 16 disposed in a horizontal plane between the lugs 20 and 21. Upon completion of playing of the record, the arm 16 will have moved past the lugs 20 and 21 so as to lie at the opposite sides thereof. The lever 14 is then lowered so as to raise the tone arm and connected part to the full line position of Figure 2, for disengaging the stylus from the record, and then the lever 14 is turned toward the right so as to again return the tone arm to an inoperative position, where it is out of the llll Way for permitting free placing of a new record upon the turn-table. WVhen the lever 14 is thus turned to the right, the member 26 engages the inclined lower edge of the lug 20 or 21 disposed in its path and is thereby caused to tilt against the action of the weighted end portion 28 so that the arm 16 may readily pass this lug. As soon as the member 26 passes the lug, it again swings back to normal horizontal position, so as to be properly disposed for engaging the flat side of the lug when the tone arm is again swung for playing a new record,

From the foregoing description it is believed that the construction and operation, as well as the advantages of the invention will be readily understood and appreciated by those skilled in the art.

Minor changes may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim as new, and desire to secure by Letters-Patent, is:

In a phonograph, a vertically disposed shaft journalled for turning movement, means for raising and lowering the shaft, a tone arm mounted upon the shaft, a stop arm carried by the shaft, a member pivoted upon the stop arm and having an end portion projecting beyond the end of the stop arm, a slide member mounted for movement parallel with the shaft, means for moving the slide member, and a lug carried by the slide member and disposed toward the shaft.

In testimony whereof I aflix my signature.

HARRY T. TULARE.
